2 Claims.

This invention relates to improvements in statistical machines and more particularly to improvements in such machines which are adapted to be controlled by light modifying control elements such as photographic film records. Such controlling fllm records may be provided with machine control representations of various data characterizations so as to provide an imperiorate and more compactly organized control record for controlling such machines than perforated statistical machine control cards through which sensing elements extend for controlling such machines.

filed May 11, 1938, be. described-briefly; Film control r rssmeh Referring now to rig; :1' wherein tary section of the photographic film controlling element is shown and generallydesignate'd ill, 7

the perforations designated 1 If representthe feed apertures in the film. The data represented at Illl represents a photographicfacsimile. representation of a document, such as a. check. and the spot representations reference numeral 202 represent-amounts which may be derived from hand set-up devices of a calculating machine or from any suitable source.

In practice, such data representations may be used to designate the depositor's number or like data and may represent or be indicative of certain classification data. The data represented by reference character 20! represents numerical data which may be obtained from different suitable sources, for example, it may be entered from the keyboard of the calculating machine. In the delineated illustration such data 203 represents the amount of the check represented at 20!.

It may be understood that the completed film has photographic reproductions thereon at successively spaced intervals along the film and that the reproductions are in extremely compact form. Accordingly, a large quantity 0! statistical information can be placed on an extremely small controlling record. The films used may be negadesigiiated by the tive films or films which during development are reversed to positive. The film delineated is a positive.

The spot representations 202 and "I are photographic machine control spot representations and each set of numerical data comprises one or more control spots in such relative position upon the film record as to represent by their relative position thereon the numerical control value thereof when the film record is trans-illuminated in the statistical machine. In practice and according to the embodiment shown, such numerical spot representations are shown on the film in index point relation in general conformance with the manner in which index perforations are disposed on perforated record cards in the Hollerith accounting system. That is, the differential position of a control spot photographic representation delineates the numerical value of a particular numeral.

In the use of the improved. controlling record in a statistical machine the film may be fed through the machine in any suitable manner and trans-illuminated and scanned to ascertain the control value of the control representation in a row or of control representations in a plurality of rows. The controlling record is effective to modify the rays of light to establish different control circuits which in turn are effective to control the operation of the statistical machine control elements. It is recognized that the control circuits and the statistical machine control elements may differ in structural arrangement and form from the illustrative devices shown in the accompanying drawings which, it is believed. represent the simplest arrangement showing the method of controlling statistical elements in accordance with coded indications or representations appearing on light modifying control records.

First, a description will be given of one method of accumulating the diiferent items and data represented by the coded indications on the control records, including briefly a disclosure, how. in lieu of or in addition to accumulating the said data. control elements may be provided or employed so that the data characterizations scanned or analyzed on the control records may be imprinted upon a suitable sheet or record. Following this, a description will be given of a method of controlling automatically the auxiliary operations of the statistical machine from the coded indications appearing on the control record, for example, automatically controlling the machine in a definite manner depending on whether or not certain of the coded indications on the control records are in agreement with predetermined data stored in suitable settable devices included in the machine. Other examples of different controlling operations will follow thereafter.

Continuing now with the description and referring to Figs. 2, 3 and 4 (arranged as shown in Fig. 8) and Fig. 6, the film record, generally designated I", is shown to be arranged to be advanced in the direction indicated by the arrow so that the control representations or spots are presented to a sensing or analyzing station where the film is trans-illuminated by a suitable light source Ill, The rays of light are modified by the control spots to control the action of the light responsive device or cells 2| I which in turn affect the action of the associated amplifying units lll. Control circuits including controlling relays A-i to Q are conditioned by the corresponding amplifier units to control the operation of said relays which in turn are effective to render operative the accumulating means control magnets and/or the printing means control magnets.

The principle of operation of the disclosed statistical machine is based on the fact that the film record having control representations thereon is presented to a sensing station and the said representations are analyzed while the film is in motion to initiate differentially timed electrical impulses in accordance with the disposition of the representations to control data accumulating of such and/or data printing mechanisms; said mechanlsms adapted to be operated in synchronism with the film record advancing and sensing means so that upon initiation of the diflerentially timed impulses which control the operation of the mechanisms. the data entered in the accumulating mechanism and the data recorded by the printing mechanisms correspond to the coded data control representations sensed. It is to be understood of system is merely an example of the principles of controlling a statistical system,

The statistical machine shown in Figs. 2, 8 and 4 comprises generally three units. namely, the film record advancing and sensing unit, the accumulator unit and the printing unit. Each unit as illustrated shows only the main control elements thereof as well as the main connections between all the units: however, the units are operated in synchronism practice at the present time. The brief description of the machine to follow is believed to be suiilcient in view of the fact that the units and method of operation thereof are predicated upon the structures shown in 531 and 1,976,617 and wherein the accumulatin and printing and associated control mechanisms are explained and described in detail.

Film advancing and data sensing means In Fig. 2, the film record we is shown'disposed magnet 229 the dog 232 is on a supply reel 2i! and attached to a] driven take-up reel ill. The film is advanced-through the agency of the motor Ii! byv means-oijthe driving connections'generally designated It ll-lid 35 Iii. The driving connections 9 are'secured't'o the shafts ill and 2.2! which have suitable ad-;

A flexible driving connection is the shaft ill and the take-up reel-Iiigenerally designated 2. It is seen now that by means of the described driving mechanism the film record may be advanced so as guide plates 225 to present the different data representations thereon to a sensing position generally designated 22! whereat the representations are analyzed in the following manner.

providedfbetween The rays of light emanating from the light source 2ill are directed upon the film record I99 at the sensing position 226 by means of a suitable condenser 221. The guide plates 225 extend across the entire width of the film and are disposed on both sides thereof. plates is provided with a series of apertures Mil-a disposed in a transverse line with respect to the film. The apertures are so spaced as to be disposed opposite the individual rows where control spots may appear upon dimensions so as to be substantially the same as the control spots. Associated with the film record and in close proximity thereto are suitably disposed a plurality of light conducting quartz rods 228 which light responsive devices or cells Ill. The said rods are positioned so that a rod may be provided for each row of control representations disposed on the film. and are arranged so as to extend into the apertures ated guide plate 22!. Consequently, when there are no control representations or spots interposed hetween the light source and the light responsive devices or stated in other words, when no control spots are to be fed through the 5 Each of the said the film record, and are extend individually to the tit-a provided in the associpresented to the sensing starotated continuously as long as now effective to advance to be operated by the control lever ing data and tion or apertures in the guide plates, the rays of light are conducted by each rod to the corresponding light responsive devices to afiect the devices in a definite manner. However, whenever a control spot or group of control spots are presented to the sensing station, the said spot or spots are efiective to block on at that position the light irom the corresponding rod or rods to afiect the action of the associated light responsive devices in a different manner. The operation of the control circuits associated with the light responsive devices will be described hereinafter.

Diiierent control devices associated with and forming part of the film advancing means will now be described. A film feed clutch magnet 22! (Fig. 2) is provided to control the feeding or advancing of the film record. Suitably secured to the armature m of the said magnet is a stop lever iii adapted to cooperate with an extension 01' a pivoted dog member 232 which is mounted on one oi the gears of the driving connections designated 2!! as shown in the figure. The said dog member when released (upon energisation of the magnet 229) cooperates with the clutch member 233 secured to sleeve 2" and the associated gear of the driving connections desi nated Ill. The said gear, sleeve and clutch member are rotatably supported on shaft iii and the motor I" is operated. Upon energization of the control released by the displaced stop lever "I. to engage the clutch member 233 thereby rotating the shafts 220 and III in unlsonwith the clutch member by means of the gearing m. Rotation of the said shafts is the film record I from the supply reel lit to the driven take-up reel Iiii. It should be stated that control contacts F-2 are provided and suitably disposed so as 23!. According to the instant arrangement the said lever is arranged to maintain the contacts F--2 closed as long as the film record is advanced past the lever. In the event of breakage of the film or that the film supply is exhausted, the said lever is then eii'ective to swing out into the plane normally occupied by the film to permit the contacts F-2 to be opened.

Data accumulating means.

The data accumulating means (Fig. 3) to be described is capable of either adding or subtractis operated in synchronism with the film. advancing means by means of the gear I", secured to the shaft I, engaging the main driving connections designated Ill. Shaft Ill, therefore, is rotated continuously as long as motor 2" is operated. and in timed relationship with the rotation of shafts 220 and "I (Fi 2). The data adding control mechanism will now be described.

The continuously rotated shaft III has slidably mounted thereon but keyed for rotation therewith a plurality of clutch elements 2, there being one for each denominational order of the accumulator. The element 242 is provided with a groove in which fits the end of an arm 2" of a suitably pivoted lever I. The said lever is normally held in the position shown by armature 245 of the control magnet III. Upon energization of the control magnet the associated armature is attracted thereto. thereby releasing the lever 2 which is positioned by the leaf spring 242a to cause the clutch element III to move into engagement with cooperating eeth I" integral with a gear I loosely mounted on shaft Ill. Gear 2. when thus coupled to shaft I. will rotate a gear III which meshes therewith and displace the associated accumulator index wheel Ill. Atso driven by gear I is a gear III which is displaced in the same manner as index wheel ill. The ratio of gears I" and ill is one to two so that the latter will turn through half a revolution for each revolution of the former gear. Carried by and insulated from gear ill is a pair of electrically connected brushes III, one of which cooperates successively with the conducting segments 2" while the other cooperates with an arcuate conducting strip Ill. The relationship of the parts is such that when the index wheel III is in its zero position, one of the brushes In is in contact with the zero segment and the other brush is in contact with the conducting strip, thus forming an electrical connection between the two. The positioning of the said brushes provides a convenient electrical read out mechanism for controlling total printing operations, the method of which is well known in the art.

It is to be understood that the control magnets Ill may be energized at various points in the cycle of the machine. depending upon the disposition of the control representations upon the film detected by the sensing means. This energization may take place in response to the detection of a control representation in any of the index point positions represented by the accumulater. The control representations are disposed on each frame of the him in such a manner, and the film advancing means and accumulator means are operated in such timed relationship that. for example. a control representation sensed in the "9 position, indicated on the film, will cause the clutch element 242 to be tripped to position the index wheel 2" and brushes 282 nine steps before a declutching operation is effected by the machine, and the sensing of control representation in the "1 position will cause the clutch element to be tripped to position the said index wheel and brushes one step before declutching thereof. For further detailed description of the accumulating mechanism reference should be made to the said U. 8. Patent 1,976,617 and wherein such well known accumulator operations, as denominational order transfer, restoration of the clutch elements and magnet armatures to normal position and resetting of the accumulator mechanism are specifically described. The resetting mechanism is shown diagrammatically to comprise a manually operated reset crank 26! secured to the shaft 28! carrying gears 2 which when operated restores the index wheels and readout mechanism to normal position in a manner well known in the art.

The data subtracting control mechanism will now be described. Subtracting in the present machineisofthetypeknownintheart asdirect subtraction, that is, it is distinguishable from statistical machines in which the amount to be entered is ilrst converted into its complement and then additively entered by the adding mechanism. In the operation of the present accumulator means, the entry of the nines complement of a number to be subtracted is effected by. initially tripping all the adding control magnets Ill as though to add nines in each pomtlon and permitting the control spot representations to cifect de-clutching of the adding mechanism in accordance with the diiierential positioning of the said representations. This will result in the addition of the nines complement of the number. The elusive one is added into the units order of the accumulator independently to change thereby the nines complement to a tens complement. Bubtracting operations of the type referred to are well known in the art. therefore, it is deemed sufilcient to present only the following brief description of the subtracting control mechanism. For a detailed description of this mechanhm reference should be made to the U. 8. Patent 1,976,617 referred to hereinabove.

A plurality of clutch elements 2", one for each denominational order position of the accumulator means, are provided and secured to shaft 292 which is rotated by suitable driving connections so that the shaft 202 rotates two revolutions for one revolution of shaft 2". An individual clutching dog I pivotally mounted on cam Ill (freely mounted on shaft 292) cooperates with each clutch element Ill also freely mounted on the said shaft is a triple armed member Ill, one

of the arms of which engages a pin 2" secured to the free end of dog 29! to hold the latter out of engagement with the driving clutch element 2H. Each of the arms of member I" cooperates in turn with a pawl 281 mounted on the clutch element Ill which is pivoted at 298. The associated pivoted armature III of magnet III is effective upon energization of the dog "I with the driving element III. will thus be driven in a counterclockwise direction until the next arm of member 2 is engaged by pawl 297, which then causes disengagement of the clutch and interruption of further movement of the cam.

Upon movement of cam 2", the higher concentric portion thereof depresses roller II! and with it the slider element I", which engages bell crank 30, to move arm 2 in a de-clutching direction at a time determined by the time of energization oi magnet Ill.

The mechanism by means of which the elusive one is entered into the accumulator means is illustrated in Fig. 3A and is more fully disclosed in U. 8. Patent No. 1,976,617. The units order of the accumulator means has associated therewith a magnet III, the armature II! of which is secured to the carry lever latch III of the units order so that energization of the said magnet is effective to trip the units point carrying arm Ill, whereby, during the carrying period of the machine cycle, the pawl ill! associated with the units order advances the units wheel one step.

Data printing means The printing or listing unit comprises a printing control cam I'll secured to the sleeve 2'" rotatably supported by the shaft ill which is rotated in synchronism with the film record feed mechanism making one revolution for each individual frame fed and analyzed, whenever the list clutch magnet 212 is energized to release the Divoted do'g member 213, which is secured to sleeve ill. to engage the clutch member i'li'secured to shaft 2 and continuously rotated thereby rotating the printing cam in unison with the shaft 2.

The member 218 is shown to cooperate with and be actuated by a cam groove in the printing en in printing bail or member I" is co ve to impart an upward movement to thetypebarstllbymeansofthe csllientconmagnet to rock supported by member 2" necticns such as springs 219 between the type bars and the printing bail. The type bars are provided with a p urality of ratchet teeth 280 which cooperate with stopping pawls 28l so that the type bars may be interrupted at various positions to present any of their type elements 282 to the printing platen 283 for cooperation therewith.

By virtue of thevsaid spring connections, the type bars may be interrupted without interfering with the upward movement of the printing ball which has an invariable extent of movement controlled by the printing cam. Energization of any one of the control magnets 21 is effective to rock the spring-pressed pivoted latch 2M releasing the associated pawl 28l so that it may swing into engagement with teeth 280 and interrupt the further upward movement of the corresponding type bar 218. The energization of the printing control magnets may be controlled directly by the sensing means upon detection of the control representations on the film record. and due to the synchronization of the type bar travel with the passage of the control spots by the sensing station will present the type elements 282, corresponding to the data control spots. in printing position.

Associated with each type bar 2181s a printing hammer 285 which is positioned to strike the type elements 282 which are now in printing position to effect printing therefrom. The printing hammers are actuated immediately after the positioning of the member 216 to the upper ex tremity of its movement. The detailed operation of the printing mechanism just described is well known and also is completely described in the said last mentioned patent, so that further disclosure of this mechanism is deemed unnecessary.

In addition thereto, control cams 256 to 259 inclusive are secured to shaft 2 and rotated thereby to operate the suitably disposed contacts C-2 to C5 for various control purposes to be described hereinafter. An additional cam member 260 is provided and secured to said shaft to operate the associated controlled contacts C-l. The said cam member is provided with a plurality of suitable camming surfaces capable of operating the said associated contacts each time the film is advanced to present to the sensing station a different incremental area of the film record wherein one or more of the control spots may appear upon the film record. The different control spots are disposed in the proper position in each individual frame of the film record so as to maintain the timing arrangement described between the said areas where control spots may appear on the film and the cam memher 260: secured to shaft 2 and insulated therefrom are a pair of electrically connected brushes ill), one brush engaging the individual conducting segments 3 while the other brush engages the common arcuate conducting strip III. The timing oi this emitter device E-i is such that a brush 3m successively engages each of the segments lll during each sensing interval.

Operation of the machine Referring now to Figs, 6 and 6A (arranged as shown in Fig. 8A), the different control circuits established by the analyzation of the controlling photographic film record will be explained. Assuming that the film record has been positioned in the film advancing mechanism and also has been positioned in proper frame eizgnment, the line switches 335 are then closed to complete circuits to the drive motor 2" and the light source m. Operation of the motor causes the various driving connections to rotate as described herelnabove. when the machine is in the normal "D" position (see Fig. '7), no control representations are present at the sensing station; therefore, the rays of light directed to the apertures in the guide plates 225 are conducted by the quartz rods to the associated light responsive cells 2 to activate them, controlling the amplifying units 2l2 (assuming that the proper potentials are applied to the control elements of the amplifying unit).. The said amplifying units may be of any known construction and arranged so that when the said light responsive cells 21! are activated, the grid elements of the amplifying units are biased to such a degree that substantially no current fiows in the output circuit of the said units. Under these conditions the relays A-l to A6 included in the respective output circuits of the amplifying units remain deenergized. It is realized now that whenever a control representation is presented to the sensing station to interrupt the light rays, that is, to prevent the light rays to impinge on the light responsive means 2, the corresponding amplifying units are conditioned to permit current to flow in the associated output circuits thus energizing the relays A-l to A6 included in the said output circuits.

Now assume that the print control switches 34! and 342 are in the "o position and the start key is operated to close the associated contacts 236 to complete a circuit as follows: From one terminal of the supply source via conductor 231 through normally closed contacts 338 of the stop key, contacts 238, common conductor 339 through: (1) the coil of relay R-l to the other terminal of the supply source via conductor 340, energizing said relay. (2) the film feed clutch magnet 229 to conductor 340. energizing said magnet, (3) the said print switches 3M and 342 through the clutch magnet 212 to conductor 340, energizing the said magnet. Energization of the firm feed clutch magnet 22!! is efiective to release the dog member 232 thereby causing the shafts 220 and 22l to rotate and advance the control representations on the film record to the sensing station. v Film feeding continues as long as the said control magnet 229 remains energized. A holding circuit for relay R--l is established through contacts 338, contacts F-2 and contacts R,la thus maintaining the said relay and clutch magnet 229 energized until the contacts 338 or F-2 are opened. Energization of the clutch magnet 212 is eifective to release the dog member 213 to rotate the printing cam 21!! and operate the associated mechanism as long as the said magnet remains energized.

Now that the machine is conditioned as described to render operative the various driving connections, the film feeding mechanism is effective to advance the differentially positioned control representations disposed on the film record to the sensing station for analyzation, and also at the same time the accumulating and printing control driving connections are operated in synchronism with the film feeding mechanism so that upon conditioning of the control circuits by the detection of any desired control representations the said accumulating and printing means are rendered operative at differential times to accumulate and/or print the data in accordance with the data control representations The said operations should be understood at this time from the foregoing description: however, the control circuits conditioning the machine for controlling directly the accumulating and printing units by means or the film record will now be described briefly. Certain features included in the description to be set forth are disclosed and described in detail in the co-pen'ding application Serial No. 207,281, flied May 11, 1938, and are claimed therein.

Upon presentation 01' the data representations to the sensing station, the light rays influencin the corresponding li ht responsive cells are intercepted or blocked so that the said cells iii are effective at such times to condition the associated amplifying units III to become conductive, or stated in other words. the said units are conditioned so as to permit current to flow in the associated output circuits. thereby causing the corresponding relays A-i to 11-4 to be energized as long as the light rays are intercepted.

Energization oi the relays A-l to A-6 is effective to close the corresponding control contacts A-la ton-6o. Now mume that it is desired to efl'ect statistical operations in accordance with the data representations present in certain of the rows or columns on the film record adapted to condition the corresponding control circuits including the relays A-I to A-I. Assume also that it is desired to add and print the corresponding data sensed; therefore, for these conditions the machine should be plugged so that the control contact plug sockets numbored I, 2 and 8 are connected individually to the adding magnet plug sockets numbered 68 to 60 respectively and also to the printing magnet plug sockets ii to 53 respectively.

It is now understood that with the described circuit conditions, whenever control representations in the said selected rows or columns are presented to the sensing station to intercept the light rays, the corresponding light responsive cells III are efl'ective to condition the associated amplifier units ii! to permit current to flow in the output circuits thereof, thereby energizing the relays A-l to A-4 and eilecting closure of the associated contacts Ala to A-la at the particular time intervals the light control representations intercept the light rays. Closure of the said contacts is eflective to initiate diflerentially timed control impulses in accordance with the control data sensed by virtue of establishing the following circuits: Conductor I", cam controlled contacts Ci (see Fig. 7), contacts A-la to A-4o. conductors connecting said plug sockets, adding magnets Ill of the accumulator and printing magnets 2 to conductor 0.

The said control magnets III and 2 are energized at the particular and diflerential time intervals the data representations are sensed thus rendering the said magnets eilective to control the adding and printing means to add and print the data in accordance with the control data sensed on the film record. Energization oi the control magnets ill causes the clutch elements 242 to be tripped to displace the index wheels I" and readout brushes "2 accordingly; and energizatlon of control magnets 2 causes the pawls ill to be tripped to interrupt further travel the type bars thus positioning the proper type element opposite the printing platen for an imprinting operation.

accuse It is obvious, of course, that the machine may be conditioned by the plug connections tor adding only and for printing only by omitting either of the plug connections to the respective control magnets.

Assume now that the contact plug sockets are connected individually to the subtracting control magnets and that the cam controlled contacts 0-! are connected to the adding control magnets 2i! and the elusive one control magnet 805 as shown in Fig. 9 and assuming that a series of individual groups of control representations are presented continuously to the sensing means, the following control circuits are established to control subtrsctively the accumulating means. It is seen that at the beginning oi each machine cycle the cam controlled contacts 0-2 are closed to establish a circuit from conductor 331 through said contacts and the conductors connecting plug socket 25 to plug sockets 68 to 69 (see Fig. 9) to the adding control magnets III to the conductor 340 thus energizlng said magnets to trip the clutch elements 242 and effecting displacement or the index wheels 250 as though nines were added in each position. Upon presentation oi the spot control representations to the sensing station to intercept the light rays, the corresponding light responsive cells III are effective to condition the associated amplifier units 2|: to cause operation of the controlled relays A-l to A-3. Closure of the corresponding contacts A-lo to AIa at the particular time intervals the said representations intercept the light rays cause the subtracting control magnets "I to be energized to efiect de-clutching of the adding control mechanism in accordance with the differential positioning oi the representations. These control circuits can be traced as iollows: conductor III, contacts C-l, A-l to A-I, conductors connecting plug sockets i-I to plug sockets "-46 (Fig. 9), magnets IN to conductor I. Energization of the control magnets 30! causes the associated dogs 29! to be released and engage the corresponding driving elements Iii thereby rotating the cams 2 thus positioning arm I in a de-clutching direction. In this manner the nines complement of the sensed data is added to the accumulating means. The elusive one is entered into the units order of the accumulating means independently by means or the control magnet 305, which is energized at the beginning of the machine cycle upon closure of the said contacts 6-! to trip the pawl carrying arm 308 so that during the carrying period the pawl 30! associated with the units order is eil'ective to advance the units wheel one step, thus effecting a change of the nine complement to a ten complement.

Automatic control operations The methods tor eil'ecting automatically various control operations of the machine will now be explained. For example, it maybe desired to control selectively the same accumulating mechanism so as to be operated additlvely or subtractively in accordance with certain o! the spot control representations presented to the sensing means, that is, it may be desired to add into the accumulator means the data represented by the control representations with the exception of certain predetermined groups or sets at control representations and subtract the latter from the amount set up in the said accumulator; or it may be desired to add to the accumulator the data represented only by certain predetermined groups of control representations and subtract therefrom the data represented by certain other predetermined groups of control representations. It. will be obvious from the description to follow that many other results and combinations may be eil'ected which are intended to be encompassed in the present invention.

The method for eii'ecting the above-mentioned results comprises first sensing the data representations and comparing the sensed data with predetermined data retained or stored in suitable settable means. then controlling selectively, during a later machine cycle. certain control circuits in accordance with the data sensed, depending on the condition whether or not the sensed data and said predetermined data agree.

The control elements providedto eflect conditioning oi the said control circuits in accordance with the sensed data at a later timed interval will now be described.

ReierrlngnowtoFigs. 2 and5,itisseen that the driving connections 2|. rotate the associated gear iii and shaft Iii whenever the film feeding mechanism is rendered operative. The said shalt is driven at a definite rate relative to the movement of the film record and carries cycle wheels ill, which are secured thereto (one for each desired row or column of control representations), having two sets of notches, each corresponding to the positions for the control representations in any given row or column 01' the film record, and these wheels make one complete revolution during the period required to advance two consecutive groups or sets of control representations past the sensing station. The D position of the wheels 3" is shown in Fig. 5.

n the shaft SIG are loosely mounted three arms III, Ill! and 320 to each of which is pivoted a spring actuated dog III, 322 and 323. one end of which fits into any one of the notches in the wheel ill. and the other projects radially outward along the arm. and assuming, for the moment, that dog 12! in engagement with a notch in the wheel has been brought by the movement or the latter into engagement with the lever lfl'while in its latched position, it is upset or thrown out of engagement with said wheel and stops in the position indicated in Fig. 5.

The movement of the parts is so timed that at the time a control representation of a given value is passing the sensing station to efiect energization of the magnets 325, a notch in wheel I" 0! corresponding value will be wider the dog Iii. The energization oi said magnet will. therefore, permit the engagement of the dog with the notch in the wheel 3" which corresponds in value to the then passing control representation on the film record. 11' no control representation in a given row or column is on the film record, the K notch will be engaged by the dog under conditions to be hereinafter reierred to. After engagement, the arm til is carried in the direction shown by the arrow and moving in unison with the wheel.

A cam wheel I! is constantly rotated by suitable gearing (not shown) which may be cooperating with gear Illand it has a number oi teethor points which knock back the lever 324 and relatch it before the next notch has come into position and before certain contacts D-I to 11-! are operated. These contacts are arranged to be operated at the same instant that the correspondingly numbered index point position on the film record is passing the sensing station.

Following the locked dog in its travel with the wheel til, it reaches at a given time the contacts D-i and the end of the arm I! engage a lever 821, operating these contacts, namely, closing contacts D-i. The said arm being still locked by its dog, continues its movement to the point in which dog I2! is shown, where it encounters a latch lever 328 and is thrown out of engagement with the wheel Ill. Here it rests until a cam 329 revolved by any suitable gearing in the machine unlatches lever "I and allows the dog to engage with an S notch in the wheel 31! by which it is carried on to the starting point where it is again unlocked by the lever Considering now the other arms 3i! and 320 and their dogs I21 and 823, each one goes through the same operations as described, but successively. That is to say, while dog "I is unlocked and stationary, the arm 3|! is being carried down to the contacts 13-4 and the dog 323 is being carried up to the latch 82!, where it will rest until the B notch on the wheel comes under it, when it is tripped by the cam 32!. Associated with the levers 324 and 328 are lock latches 330 which engage the arms after they have been freed from the wheel and prevent any backward movement of the same.

I! no control representation is in a given row or column the corresponding magnet 32! will not be energized and under these conditions the uppermost dog 32! must be released to engage the K notch. This is cflected by knock-oil cam a1 rotated by any suitable gearing so that the high point engages the latch lever 332 and withdraws it from engagement with the lever 32, once near the end 0! each cycle.

The cams 326, 329 and ill referred to are driven by suitable gearing which in turn can be driven by gear lit (Fig. 2) or by a similar gear secured to shaft iii. The relative timing of the cams with respect to the operation of the wheels 3" and associated dogs "I to 123 has been set forth hereinabove.

Data comparing method.Reierring now to Figs. 6 and 6A (arranged as shown in Fig. 8A) and Fig. 7, a plurality of manually settable devices Si to Si2 are shown atically, each comprising a common conducting strip or ring 5 and a plurality of individual conducting segments 6 which are electrically connected to the said common ring by means of the positionable connector brushes 3". The said manually settable devices are similar in construction to the readout devices shown in Fig. 4 of U. 8. Patent 1,976,61'1. The individual conducting segments of all the said devices are connected to the individual segnfents 3 of emitter E-i. Now assume that certain predetermined data are represented or stored in the settable devices S-l to S3 due to the diilferential positioning of the connector brushes, and assume that this said predetermined data is to be compared with certain classification data represented by the control spot indications disposed on the film record and effective upon sensing thereof to control the operations oi relays A--I to A-4, and further assume that the individual plug sockets l to 3 are connected to plug sockets I! to 72 respectively.

Upon presentation of the groups of the classiiication spot representations to the sensing station, the relays A-i to A-8 are controlled by the associated light responsive means and amplilier units in exactly the same manner as described hereinabove, so as to be energized upon interception of the light rays by the said spot representations. It will be seen therefore, that upon energization of the said relays and closure of the associated contacts A-la to A-la that whenever the aid data sensed is in agreement with the data set up in the devices 8-! to 8-4, the corresponding CRv-I to CR-l relays are energized, due to the synchronous operation of the emitter'E-i and the film record feeding means. The control circuits established under these conditions are as follows: Conductor 331, contacts C-i (see Fig. 7), contacts A-la to A-Ia, conductors connecting the plug sockets l-4 to plug sockets ll-l2, pickup coils of CR--l to CR-S relays, settable devices to 8-4, emitter E-l to conductor I, energizing said relays, thus efl'ecting closure of the contacts CR-la to Cit-Ia. Holding coils are provided for the said relays and are designated CRH--l to CRH-4 which are now energized as follows: Conductor 331, contacts 0-5 (see Fig. '7), contacts CR-la to Cit-8a., holding coils CRH-J to CRH-i and conductor I. The relays CRI to 03-! are maintained energized until contacts 0-5 open near the end of the machine cycle. Contacts (JR-lb to CR-lb are also closed upon operation 01' the said CR relays to establish the following circuit near the end of the machine cycle: Conductor I31, contacts 0-4 (see Fig. 7), contacts (YR-lb to Cit-3b, coil of relay 11-2 and conductor 3, energizing said relay, and operating the associated contacts It-Ia and lb. A holding circuit for the said relay is established through contacts R-Ja as follows: Conductor 831. contacts 0-4 and 3-20, coil oi relay 3-! to conductor Ill, and by means of contacts 0-4 (see Fig. 7) is maintained energized until near the end of the following machine cycle.

Due to the closure of contacts R-la to R-lc. circuits are established from plug sockets 21 to 24 to plug sockets It to II by means of the connecting conductors shown in Fig. 10 through the normally closed contacts R-la to R-Jc thus connecting the adding control magnets III to the delay contacts D-i to 20-3.

It was explained hereinabove how the energization of magnets 325 is effective to control set up in the settable devices 8-! to 8-1 to Selective control methods-Now assume that the circuits shown in Figs. 6 and 6A are connected s indicated in Fig. 10 and that it is desired to control the accumulator means selectively in accordance with predetermined classiflcation data disposed on the film record. Assume the classification data to be disposed in columns 1 to 8 (see Fig. l) and the amount data to be entered in the accumulator means disposed incolumnsitofiandthatthedataintheflrst mentioned columns are eflective to control the operation of relays A-l to A4 and the data in the second mentioned columns eflective to control relays A-4 to A--6. The said assumptions regarding the disposition of the classification and amount data is not to be confused with the data shown disposed in certain columnar areas oithefllmrecordshowninFig. l. Itisunderstoodthatsuchdatacanbedisposcdinany desired columnar areas. In the said figure cer tain disposition of certain data, which is related to the document facsimiles thereon, is shown, whereas an assumption is now made altering the disposition of the classification and amount data which is done to simplify the description to follow.

Continuing now with the description. closure of contacts R-Ib establishes a circuit from conductor I" to contacts It-Ib, conductor connectingplugsocketslland38(see1"lg.10) tocoil of relay 3-1 and conductor 8, energizing said relay, thus operating contacts R-Ia to lit-U.

control the operation of relays 3-2 and R-l to establish circuits between the delay contacts D-i-tu D-3 and the adding control magnets ii! in the event that the sensed data and preset data agree. and that the said circuits are maintained energized for the following machine cycle due to the timing of operation of the cam controlled contacts 0-], C4 and (2-5 (see 18. 7).

It is also seen that under the conditions Just described the amount data representations disposedincolumnsi,5and6,andiormingpart of the group of representations of which the class data agreed with the preset data, are efiective to operate relays A4 to A-4 and the contacts A--lu to A--6a to energize the corresponding magnets 325 thus storing the sensed data for a machine cycle and thereafter control the operation of the associated delay contacts Dl to 13-3 in accordance with the data representations sensed to control the operation of the adding control magnets Iii (through the circuits conditioned and described when the sensed and preset data agree), thus cil'ecting entry into the accumulator means of the selected amount data representations.

It is obvious that 11' it is desired to print or list the selected amount data instead of entering the data into the accumulator mechanism, that the plug connections from sockets II to II may be connected to the printing control magnets Iil instead 01' the adding control magnets 2 it. In this event it is desirable to prevent spacing of the record sheet except when printing. To this end, additional control circuits are provided so as to control the printing means clutch control magnet Ill through contacts R-lg. The control switch "I is then set in the "on" position, therefore whenever the sensed classiflcation data and preset data agree relay R-l is operated as described hereinabovc and operation of contacts Rr-Jq is eiiective to complete a circuit from conductor 311, through stop key contacts ill. contacts F--! and 3-40. switch 3, contacts l t-lg and R--ld to the clutch magnet 21! and conductor I thus operating the printing mechanism only when the class data agrees with the preset data.

It will now be shown how the amount data disposed on predetermined film records are entered selectively into the data accumulating means; for example,' whenever the classification data onthe film records is compared with the data stored in the said settable devices and are found to be in agreement control circuits are established to prevent entry of the related amount date on the said iilm records. By referring to Fig. 11, it is seen that the circuit connections are somewhat similar to those of Fig. 10 with the exception of the connections from plug sockets II to II to the adding control magnets by means 'ofplugsockets "to". Duetothischangein circuit connections the data sensed in columns 4, and 6 is permitted to control theoperation of the adding control magnets I II as long as the data sensed in columns 1, 2 and 3 and the preset data disagree by virtue of the following circuits: Conductor 331, contacts C-l, contacts 'D-i to 13-1, conductors connecting the plug sockets 1-0 and plug sockets ll-2| shown in Fig. 11, contacts R-ld to R-lf which are normally closed, normally closed contacts R-la to 8-60, conductors connecting plug sockets "-45 and plug sockets "-80 shown in said figure, control magnets ill to conductor I. As long as the compared data disagrees the circuits lust traced are maintained, however upon agreement of the compared data, the control circuits for relays Cit-I to CR-l are energized (these circuits have been traced hereinabove and therefore are not repeated at this time) to energize relays lt-Z and R-l. As explained hereinabove energization of relay R.l is effective to open contacts B-1d to R-lj and close contacts R-lo to R-lc, thereby opening the control circuits leading to the control magnets III thus preventing encrgization of the said magnets at such times whenever the compared data agrees. In this manner entry 0! the amount data in the accumulating means is suppressed whenever the class data representations agree with the data set in the settable device.

Printing or listing of all of the amount data sensed except data of certain predetermined groups instead of controlling the accumulating means thereby, can be eifected by connecting the control circuits to the print control magnets 2 instead of the magnets Ill from the plug socket II to IS. A circuit is provided to prevent spacing of the record sheet when not printing and is as follows: With switch I in "o position and switch 342 in on position, a circuit from conductor 331 is established through contacts "I, F-I, and Rlo, switch I, contacts It-lh to clutch magnet 21! and conductor I to energize said magnet as long as the compared data disagrees. Upon agreement thereof relay Rl is energized to open contacts It-lh thus preventing further operations of the printing mechanism including the record sheet spacing mechanism.

The description up to now regarding the automatic control operations has been limited to comparing but one group of class data representations. It was mentioned hereinbefore that a plurality of manually operated settable devices B-ituB-llureprovided. Itwillnowbeseen that a plurality of these devices may be connected in multiple and thus be eflective to control or compare two or more independent groups of class data representations. Assume that it is desired only to control or compare on three columns of classification data representations, thus the groups of settable devices A," "3," "C." and 13" could be conditioned to compare four independent groups of classification data.

Whenever desired two or more of the said groups circuit connections in Fig. 12). In Fig. 12 the remaining circuits are connected as shown in Fig. 10 and described hereinabove; so that comparing of the classification data is now effected by comparing the data set up in the group of devices A. "B." C, D. fu th r the circuit connections connected as shown in Fig. 12, it is seen that data entry in the accumulator and/or data printing is suppressed not only when the classification data sensed agrees with the data set up in device A," but when the said data sensed agrees with the data set up in any one of the devices "A," "B," "C" and "DJ Controlling data accumulating means additively and subtroctivelw-It will now be described how all the amount data representations sensed except those representations disposed in certain predetermined groups are eiiective to control additively the accumulating means and how the said data representations of the certain prede termined groups are ciiective to control subtractively the same accumulating means. Briefly and broadly. this result is accomplished by comparing the class data representations with the predetermined set up data, and in the event the compared data disagrees control circuits are conditioned to add the amount data to the accumulator means; in the event the compared data agrees diflerent control circuits automatically are conditioned to subtract such amount data from the said accumulator means.

The detailed description of the method embodied herein will now follow and reference should be made to Figs. 6 and 6A (the circuits shown therein connected as indicated in Fig. 13). Similarly, as described hereinabove, the class data sensed in columns 1. 2 and 3 are effective to control the operation of relays Al to A-l, thus controlling the operation of contacts A-la to AIc which are connected directly to the set up devices S-l to 8-4 designated group A. In the, event the class data sensed disagree with the data set up in the said devices, no circuits are completed to energize the connected relays CR-l to Cit-I. During the said wnditions, relay 3-: remains deenergizcd, because the series circuit comprising in part the contacts CR-lb to Cit-lb is not completed. Therefore. relay R-l remains deenergized by virtue of the open. contacts it-2b. Thus, it is seen that.the control circuits established for the data accumulating means is as follows: From conductor 33! to contacts 0-l, contacts A-4a to A-6a. conductors connecting plug sockets 4-6 to plug sockets 45-41 shown in Fig. 13, magnets 32' to conductor 3, energising said magnets in. accordance with the amount data sensed. The associated and corresponding contacts Di to 13-! are operated during the following machine cycle to establish a circuit from conductor 8" to contacts C-I, said contacts 13-! to D.I, conductors connectin: plug sockets 1-! to plug sockets 22- as shown in Fig. 13, contacts .R-ld to R-|l via conductors ill to 352, contacts R-ta to 3-4:: to the adding control magnets lit, energizing said magnets thus effecting entry of the amount datasensed into the accumulator means. Therefore, it is seen that the said accumulator means is controlled additively by the sensed data as long as the compared data disagrees.

A However, upon agreement of the compar data, a circuit is completed fromconductor ill to contacts C-i, contacts A-la to A-Sa. conof devices may be connected in multiple (see the 76 ductors connecting plug sockets 3 t plug sockets ID-ll shown in Fig. 13. to coils oi relays CR-l to Cit-I. devices S-l to 8-8, emitter E-l to conductor "I energizing the said relays. Closure of contacts CR-ib to Cit-lb permits a circuit to be established upon completion of sensing the said data representations through contacts -4 to energize relay R-I, closing contacts R-ib thereby causing relay 8- to be energised. Energization oi the last mentioned relay causes contacts RIG to R-tc to be opened and contacts R-ld to 12-61 to be closed. It has been explained how. by means or the timed cam contacts. the last mentioned conditioned circuits are maintained during the following machine cycle. so that the stored data is eiieetive, by means or contacts D-i to D-S, to control the accumulating means. The diiierentially timed impulses initiated by the contacts D-i to D-l are impressed upon the circuits "I to I" and by means or the plug connections (see Fig. 13) to the subtracting control magnets llli, energizing said magnets at diilerent intervals in accordance with the sensed data to eiiect subtracting said data from the accumulator entries. It should be mentioned that by means 01' contacts 0-! and contacts R-t! the elusive one magnet I06 is energized at the beginnirm oi the machine cycle to effect entry of the elusive one, and also provision is made at the beginning or the machine cycle to trip the adding control magnets II! in accordance with the method of subtraction described and embodied herein, by means or the iollowing circuit: From conductor 331 to contacts C-i, contacts 0-2, conductor connecting plug socket II to plug socket 26 shown in Fig. 13, contacts R-So to R-ti, normally closed contacts R-lo to 3-80 to the adding control magnets 2 II by means of the conductors connecting plug sockets it to Hi to plug sockets 58 to 80 (see Fig. 13). In this manner the sensed amount data is effective to control subtractively the accumulating means at certain predetermined times while at other times the same accumulating means is controlled additively by the sensed amount data.

In view of the description thus far, it is understood that various selective operations may be eil'ected depending upon the initial conditioning 01 certain oi the control circuits. For example, it may be desired to have all the amount data representations sensed except those 01' predetermined groups control additively the accumulating means and control the same accumulating means subtractively only in accordance with the amount data or certain ones 0! the said predetermined groups. Such results may be attained by multiple connections of the settable devices B-l to S-l2 as mentioned hereinabove. Assume that all the amount data sensed is to be added with the exception of such data included in the groups having class data in agreement with the setting of devices A and "B" comprising the individual set up devices 8-! to 8-3 and 8-4 to 3-! respectively, and furthermore that the amount data sensed in certain 01' the said groups having class data in ent only with the setting of device "8 is to be subtracted. In this case the devices "A" and 13" are connected in multiple and the control circuits connected asindicatedinl 'ig. 14. Itwillbeseenthatall the amount data sensed except the data included in the groups having class data in agreement with the preset data in devices "A" and "2B" is eilective to control additively the accumulating means in exactly the same manner as lust described. However. when the class data agrees with the preset data in device "A" the control circuits to all control magnets 01' the accumulator means are opened by virtue of operation 0t 3-! (the specific circuits traced hereinbefore) and in turn the operation of relays 5-1 and Ill-8. The latter are energized upon closure oi the contacts R-2b through plug connections I! to It and 03 to ll. Operation oi relays 3-1 and 3-! cause contacts A-id to R-U and contacts R-lc to It-tc to open. thus preventing operation oi the control magnets oi the accumulating means. When the class data agrees with the preset data in device B, relays Cit-4 to CR-B are energized to operate the contacts CR-lbtoCR-Bbthus causingrelayRp-tto be energized and the contacts 8-31: to be operated. Operation of contacts Ib-Sb causes relay 3-6 to be energized by means oi the plug connections 40 to I! thus opening contacts R-Ba to R-Gc and closing contacts Rr-d to 3-61. As mentioned before by means of contacts 0-2 the add control magnets Ill are energized at the beginning or the machine cycle as if to enter nines in the accumulator means and the elusive one control magnet "I of the said accumulator means is energized at this time to eifect entry of the elusive one. Thus. it is seen that the timed impulses initiated by the contacts D-i to 13-8 are impressed now upon the circuits 35! to 355 to control the operation of the subtract control magnets Ill and in this manner control the accumulator means subtractively in accordance with the amount data sensed, the class data 01' which is in agreement with the preset data 0! device 53.,

Now assume that it is desired only to add certain predetermined groups 01' amount date. to the accumulator means and subtract other predetermined groups of amount data from the said accumulator means, and that the class data 01. the data to be added corresponds to the data set up in devices A and the class data of the data to be subtracted corresponds to the preset data in devices "3." For this method 0! selective control the circuits are connected as indicated in Fig. 15. The class data is compared with the preset data in devices A and "8 by means of :the circuit connections from the contacts A-ia to A-Ia. to the said devices connected in multiple to control the operation or the relay 8-2 when the class data agrees with the preset data of device "A" and the operation of relay 3-! when the class data with the preset data of device "3.

Operation of relay H and contacts R-3b is eflective to energize relay 3-! thus causing (1) the energization of the adding control magnets as though to eiiect entry of nines in the accumulator means through the contacts R-to to 5- and 0-2, (2) the energization of the elusive one control magnet I through contacts R-lj, (3) the energisation o! the control magnet ill through the contacts 8- in H1.- rmew or the ma adamia: 'contaCiSiTD- to thusfjfiohtrolllng sub,- tractivelfthe accumula'or means in accordg;

Now, as long as the class da a disagrees with the preset data of device A,"fthetirned impulses initiated by the contacts D'--l to j are impressed on the circuits 350 to 36' and the control magnets 2 (associated with plugf sockets 54 to 56) through the oontact'sf ite-ta to R-lic thus eflecting listing in a certain columnof the amount data sensed.

Listing again is eflected by the direct connections from the list magnet to the D-I to D-I contacts. To indicate the fact that certain amount data is subtracted an additional print control magnet lit-a (Fig. 6) is provided to control a type bar in exactly the same manner as the type bars 218, however, a special indication such as an asterisk my rmless! milit as?! the tim bar. thus prlnting'an indlcatingmark --8- "9" impulse through the 0-2 contacts, thus effective to permit energization of relay 'R-2 thus operating contacts R''-2b" and relay R-'1.j While the circuits are'conditioned accordingly, the timed impulses initiated by contacts lJ- -l to D& are impressed upon'circuits $-$01! to energize the add control magnets-2|! and other list control magnets 2 (associated with plug sockets 5| to 53) through contacts Rla to RS-lc and R,8a to R-8c, thus eilecting entry of the selected amount data in the accumulator means and listing the said data in a column apart from the first mentioned listed data.

Controlling data accumulating means additively and subtractively, listing all the amount data sensed and indicating the subtracting operations.-'I'he circuit connections are connected as indicated in Fig. 1'1 to attain this result, and upon examination it is seen that the circuits are conditioned similarly as shown in Fig. 13,

with the exception of the additional-lastingcircult arrangements. All the amount data sensed except the amount data included in the group having class data in agreement. with the present data of device A" is efiective to control additively the accumulator means as i'ollows: As long as the class data is dissimilar to the present data relay R-G remains deenergized. Consequently, the timed impulses initiated by the contact D-l to 13-4 are impressed upon circuits 350 to 352 to energize the add control magnets 2l3 via contacts R-ld to RP-lj and R-Ga to 8-60. At the same time the said impulses are impressed upon certain print control magnets 2 due to the direct connections from plug sockets |9 to til-53 thus controlling additively the accumulator means in accordance with the amount data and efl'ecting listing of the said data. Upon agreement 0! the compared class data, relay R-G becomes energized in a manit is seen that, whenever the circuits are conditioned to control subtractlvely the accumulator means and to list the data entered therein, an individual indicating mark such as an asterisk is printed opposite the listed data thereby indicating on the printed sheet that such data was entered subtractively in the accumulating means.

In some casesit may be desired to add and list only certain predetermined amount date and subtract and list other predetermined amount data and print an indicating mark opposite the amount datasubtracted and listed. For such machine operations the circuits are connected as indicated in Fig. 18 whereby the amount data having class data. in agreement with preset data of device A" is added and listed and the amount data having class data in agreement with preset data of device "B" is subtracted, listed and identified accordingly.

Assume switch I to be in the "on position. When the class data and preset data of device "A" are in agreement relay 3-! is operated to energize relay R,'I and close contacts R-la to R-lc, and thereby the timed impulses initiated by contacts D-l to D-I are impressed on circuits "Hi2 and the add control magnets 2!! via contacts R-ta to R-lc. Listing 0! all the amount date. sensed in said predetermined groups is efiected by control magnets I which are connected directly to the contacts Dl to D-J. It should be noted in this operation that control 01' the print clutch magnet I'll is effected by the operation of contacts R-lg and R-Bk thus printing of the data can only be etfected whenever the class data is in agreement with the preset or predetermined data. Now when the class data and preset data of device "B" are in agreement relay R-l is operated to energize relay R-6 and the associatedcontacts. Thus the timed impulses initiated by contacts D-i to 13-! are impressed upon the circuits 353-355 and the subtract control magnets till via contacts R,6d to 11-6). The accumulatlng means is conditioned for subtraction operations by means or contact lip-6c to R6i and C-2 energizing the add magnets Ill via contacts R-Ba to R.8c at the beginning oi the machine cycle.

In accordance with the operations described hereinbetore, it is evident that listing of the data sensed in separate columns may be effected. The plugging arrangement for such operations is indicated in Fig. 22. The list control magnets ill are connected to plug sockets it to II which in turn are connected to the individual accumulator means so that when each accumulator means is controlled the corresponding list control magnets are rendered operative simultaneouslytherewithtolistthedataenteredinthe particular accumulator means.

In the event only certain predetermined amount data is to be entered in one accumulator means and certain other amount data in another accumulating means, the circuit connections are conditioned as indicated in Fig. 20. Therefore, when the class data is in agreement with the preset data of device "A," relays 3-2 and 11-8 are rendered operative so that the timed impulses initiated by contacts D-l to D3 are impressed upon circuits 353-455 and the add control magnets 2!! of accumulating means No. 2 via contacts R-td to R6I thereby controlling said means additively in accordance with the amount data having class data in agreement withthe preset data of device A.

Summary It has been shown how a photographic iilm controlled statistical machine may be controlled selectively to perform diflerent data manil'esting operations depending upon the relative values of the classification data successively presented to the machine for analynation.

It has been shown how the sensed data is stored in data storing elements ior control purposes simultaneously with oomparing the sensed data with selected predetermined data retained in manually settable devices by (1) conditioning light responsive means by modified light rays in accordance with the light modifying areas disposed on the film control records: (2) controlling by means or the conditioned light responsive means the energization of selected comparing circuits thereby controlling the selection of adding, subtracting and/or printing control magnets. and (3) controlling by means of the conditioned light responsive means the enersization oi data storing control magnets to effect storing of the desired control data which is then eil'ective during a later cycle oi the machine to control the operations 01' the selected data receiving control magnets.

It has been shown that the data accumulating means may be controlled additively and/or subtractively depending upon the relative values of the classification data, also that certain operations such as adding or subtracting the amount data may be effected if the compared data is in agreement and upon disagreement thereof subtracting or adding the data respectively. It has also been shown that the data accumulating means may be controlled additively when certain predetermined classification data is sensed and controlled subtractively when certain other predetermined classification data is sensed. In addition thereto, it has been seen that printing the selected amount data may be eiiected and that opposite certain 01 the listed data special indicating marks may be printed to indicate the type oi' entry made of said identified data in the accumulating means.

While there has been shown and described and pointed out the fundamental novel features of the invention as applied to a single modification, it will be understood that various omissions and substitutions and changes in the tom and details oi the device illustrated and in its operation may be made by those skilled in the art without departing from the spirit oi the invention.
